Easy "Fireworks" trophy

Easy "Good Fences" trophy

Get on the roof of the left base, which is near the only gate they try to break down. Use Marksman turrets and Atomizer gravity wells to keep them from getting too close to the door. Also, throw some hedgehogs to act as mines. If there are too many for the Marksman or Deadeye, use the Wildfire"s primary and secondary fire to eliminate large crowds. If you cannot see more enemies, use the Auger to kill the last of them. Note: The gate must not be allowed to fall.

Easy "Juggler" trophy

Play Chapter 16: "The Pit" in Graterford, PA. Start in the cafeteria section, and collect extra ammunition and Molotov cocktails. Continue until you are attacked in the circular sewer area with waterfalls by Leeches and Grims. Note: A fully upgraded Rossmore with the flame-thrower secondary upgrade is recommended. Poison, freeze, then burn four grims, in that order simultaneously, to get the "Juggler" trophy. To gather four of them together, wait until the second round of attacks in the sewer, when they appear from a waterfall. Shoot a secondary fire cloud from the Mutator at the base of the waterfall where the Grims land. Freeze them while they are upright by switching to your Cryogun. Then, use the Rossmore's secondary flamethrower attack to set them on fire.

Easy "One Eyed Jack" trophy

Easy "Roops!" trophy

Play "The Hunt" chapter in Mt. Pleasant, PA. Malikov will say "Joseph I see you. I'm at the far side of the bridge across the river" just after you leave a mineshaft.

Get the Deadeye, and look out the window to find a building with five Grims standing. They are located as follows: one on the fire escape on the right, two on the roof directly in front, and two on the higher roof behind the building.

Easy "Slaybells" trophy
